Description |
| 41 |
=========== |
| 42 |
|
| 43 |
John Heasman of NGSSoftware has discovered a heap-based buffer overflow |
| 44 |
when parsing the "prdata" tag in RTF files where the first token is |
| 45 |
smaller than the second one (CVE-2007-0245). Additionally, the |
| 46 |
OpenOffice binary program is shipped with a version of FreeType that |
| 47 |
contains an integer signedness error in the n_points variable in file |
| 48 |
truetype/ttgload.c, which was covered by GLSA 200705-22 |
| 49 |
(CVE-2007-2754). |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A remote attacker could entice a user to open a specially crafted |
| 55 |
document, possibly leading to execution of arbitrary code with the |
| 56 |
rights of the user running OpenOffice.org. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
All OpenOffice.org users should upgrade to the latest version: |
| 67 |
|
| 68 |
# emerge --sync |
| 69 |
# emerge --ask --oneshot --verbose ">=app-office/openoffice-2.2.1" |
| 70 |
|
| 71 |
All OpenOffice.org binary users should upgrade to the latest version: |
| 72 |
|
| 73 |
# emerge --sync |
| 74 |
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.2.1" |
| 75 |
